I submitted the following T-SQL:--BACKUP CERTIFICATE EncryptTestCert-- TO FILE = N'c:\backup\EncryptTestCert.cer'-- WITH PRIVATE KEY-- ( FILE = N'c:\backup\EncryptTestCert.pvk',-- ENCRYPTION BY PASSWORD = N'T0yp0calypse'-- )--DROP SYMMETRIC KEY PrivateKey1--DROP CERTIFICATE EncryptTestCert--CREATE CERTIFICATE EncryptTestCert--FROM FILE = N'C:\backup\EncryptTestCert.cer'--WITH PRIVATE KEY (FILE = N'C:\backup\EncryptTestCert.pvk',--DECRYPTION BY PASSWORD = N'T0yp0calypse')--CREATE SYMMETRIC KEY PrivateKey1--WITH ALGORITHM = TRIPLE_DES ENCRYPTION--BY CERTIFICATE EncryptTestCert--OPEN SYMMETRIC KEY PrivateKey1 DECRYPTION--BY CERTIFICATE EncryptTestCert--SELECT CONVERT(nvarchar(50),DECRYPTBYKEY(encryptedcolumn)) AS DecryptSecondCol--FROM EncryptionTest1However, the return data just contains nulls, instead of the original decrypted data. You can see above that I deleted the certificate, but then restored the certificate from backup. However, it doesn't work.What am I doing wrong? |

Does no-one know how I can restore both the certificate and the symmetric key?Should I have asked this in one of the other sub-forums? |

The following works:--CREATE SYMMETRIC KEY myGoodkey1--WITH ALGORITHM = TRIPLE_DES,--KEY_SOURCE = 'MyKeyS0urce',--IDENTITY_VALUE = '0h n0, Identity'--ENCRYPTION BY CERTIFICATE EncryptTestCert--OPEN SYMMETRIC KEY myGoodkey1 DECRYPTION--BY CERTIFICATE EncryptTestCert--UPDATE EncryptionTest1--SET encryptedcolumn = ENCRYPTBYKEY(KEY_GUID('myGoodkey1'),testcolumn)--OPEN SYMMETRIC KEY myGoodkey1 DECRYPTION--BY CERTIFICATE EncryptTestCert--SELECT CONVERT(nvarchar(50),DECRYPTBYKEY(encryptedcolumn)) AS DecryptSecondCol--FROM EncryptionTest1--DROP SYMMETRIC KEY myGoodkey1--CREATE SYMMETRIC KEY myGoodkey1--WITH ALGORITHM = TRIPLE_DES,--KEY_SOURCE = 'MyKeyS0urce',--IDENTITY_VALUE = '0h n0, Identity'--ENCRYPTION BY CERTIFICATE EncryptTestCert--OPEN SYMMETRIC KEY myGoodkey1 DECRYPTION--BY CERTIFICATE EncryptTestCert--SELECT CONVERT(nvarchar(50),DECRYPTBYKEY(encryptedcolumn)) AS DecryptSecondCol--FROM EncryptionTest1 |
